Overview of Applicable Law

Local traffic regulations for Kennewick are codified by the city and published through the municipal code publisher; state statutes govern criminal offenses such as DUI. When a city ordinance differs from state law on administrative matters, enforcement follows the controlling instrument cited on the citation or summons. For the city code see the Kennewick Code of Ordinances Kennewick Municipal Code[1]. For DUI statutes see Washington state law at RCW 46.61.502 Driving while intoxicated (RCW 46.61.502)[2].

Speed Limits

Speed limits within city streets in Kennewick are established by ordinance or by official traffic control devices placed under city authority. Residential, arterial, and school-zone limits are set where posted or by specific ordinance sections. Specific numeric speed limits and special school-zone schedules are published in the municipal code or on official signage; numeric schedules are not summarized on the cited municipal-code overview page and therefore are not specified on the cited page.[1]

  • Follow posted limits and special reduced-speed zones near schools and work zones.
  • Observe temporary reductions for construction as signed on site.

Right-of-Way Rules

Right-of-way at intersections, crosswalks, and roundabouts follows the city traffic code aligned with state rules: yield to pedestrians in marked and unmarked crosswalks, follow stop/yield signs, and obey traffic signals. The municipal code references state statutes for standard right-of-way rules; the municipal summary page does not list every rule text and so some specifics are not specified on the cited page.[1]

Pedestrians generally have the right-of-way at marked crossings and where traffic-control devices direct it.

Penalties & Enforcement

Enforcement is primarily by the Kennewick Police Department and authorized city officers; criminal DUI charges are prosecuted under Washington state law. Municipal traffic fines, civil penalties, and administrative fees are set by ordinance and the city fine schedule; the overview page does not display line-item fines and thus specific dollar amounts are not specified on the cited page for municipal infractions.[1]

For DUI and driving-under-the-influence criminal penalties, see RCW 46.61.502; the statute describes criminal charges and sentencing ranges enforced at the county/city level and by state prosecutors.[2]

  • Fine amounts for city traffic infractions: not specified on the cited municipal-code overview page.[1]
  • Escalation: repeat or continuing offences may carry increased penalties or separate criminal charges—specific escalation schedules are not listed on the municipal overview.[1]
  • Non-monetary sanctions: orders, traffic school referrals, probation, license actions (suspension/revocation) and seizure of vehicles may apply under state or local authority; details depend on statute or ordinance cited on the charge.[2]
  • Enforcer: Kennewick Police Department enforces city ordinances; criminal DUI prosecutions occur through county/state prosecuting authority.
  • Inspection/complaint pathways: report parking or traffic concerns to Kennewick Police non-emergency or the city code enforcement contact (see Resources below).

Appeals, Review & Time Limits

Appeal routes follow the procedure printed on the traffic citation: either request a hearing in the court designated on the citation or follow the administrative appeal process described by the city. Specific filing deadlines and time limits vary by citation type and are indicated on the ticket or in the ordinance/court rules; these deadlines are not specified on the cited municipal-code overview page.[1]

Defences & Discretion

Common defenses may include a lawful emergency, official permission or permit, or an error in signage or citation. The city and courts retain discretion in enforcement and may accept mitigation or alternative resolutions where authorized by ordinance or statute.

Applications & Forms

The municipal-code publisher page and the state statute page do not host a single combined traffic-appeal form. Forms for contesting citations or requesting hearings are provided by the court listed on your citation or by Kennewick city finance/court services; if no city form is published on the cited pages, then a court form or the citation instructions must be used (forms not specified on the cited municipal-code overview page).[1]

Common Violations

  • Speeding in posted zones (school/work zones have enhanced enforcement).
  • Failure to yield at intersections or crosswalks.
  • Driving under the influence of alcohol or drugs (DUI).
